DANIEL W. HAYDEN, OF PROVIDENCE, RHODE ISLAND.

STOP MECHANISM FOR DRAWING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 227,002, dated April 27, 1880. Application filed May l19, 1879.

To all lwhom 'it may concern Be it known that I, DANIEL W. HAYDEN, of the city and county of Providence, State of Rhode Island, have invented a new and useful Improvement in Stop Mechanisms for Drawing-Frames; and I hereby declare th at the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in the construction of stop mechanism applicable to drawing-frames and cotton-sliver eveners or railway-heads; and it consists in the peculiar construction of the parts hereinafter claimed for detaching thedriving mechanism both when the sliver breaks and the trumpet becomes choked. l

Figure 1 is a view of my improved stop mechanism shown in connection with the detaehing mechanism when the sliver passing through the trumpet is of the required size. Fig. 2 shows the position of the various parts when excessive friction is produced on the trumpet by a heavy sliver passing through the same, or when the trumpet is choked, in solid lines, and in broken lines in the position occupied when the sliver is broken.

In the drawings, a c represent the drawingrolls; b, the trumpet secured to the arm b and hinged on the fulcrum c. A long lever, d, is connected by an adjustable connection to the horizontal arm of the arm b', and the lever d is provided with an adjustable weight, e, the end of the lever d being provided with a hook. Connected with the lever d by a jointed link-connection, f, is the stop-pawl g, hinged at the bottom and provided with an adjustable balance-weight, gf, sliding on a horizontal pin.

h is an oscillating arm mounted on a rocking shaft, and provided with a stud on which the V-shaped ridingpawl connected with the eccentric k rests, and by which it is oscillated so long as the arm h is free to oscillate. The arm his also provided with the hook or projection h2, with which the hook on the lever d engages when the sliver breaks, and by which the oscillation of the arm his prevented.

5o Another curved projection, h', oscillates close its friction the weight e, the oscillation of the arm h will be arrested, and when the trumpet chokes the same result will follow. 1

When the arm h is prevented from oscillating freely, the V-shaped riding pawl will be pushed over the pin and will rise, and in its turn will raise the slide l, through a slot in the upper part of which the riding lever z' passes.

m is a roll inserted in the slot at the upper end of the slide l to avoid friction. The lower end of the slide Z is connected with and operates the hinged arm n, the other end of which is arranged to disengage the shipper mechanism.

The stop mechanism may be adjusted by moving the Weights c and g. It is very sensitive in its operation, and can'be used on a railway-head by passing the cotton sliver first through the ordinary evener trumpet, by means of which the speed of the drawingrolls is regulated, then through the deliveryrolls, over and around the same, through the supplementary trumpet b, and again through the delivery-rolls to the cans, the first trumpet controlling the speed-regulating mechanism, and the second trumpet the stop mechanism.

I do not wish to confine myself to any particular kind of belt-shipper mechanism, this forming no part of this invention; but for the purpose of illustration I would refer for a description of a belt-shipper mechanism to my application for improvements in cotton-sliver eveners,iiled simultaneously with this present application.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the trumpet b and the lever b', of the arm h, having the stops, as described, and the lever d, arranged, as de scribed, to interfere with the oscillation of the arm h, and the stop g, arranged to interfere with the projection h', und provided with the I mechanism for oscillating said arm, all aradjustable Weight g', the lever l and stop g beranged to operate substantially as Cmd for the 1o ing connected by :n hin ged link, substantially purpose set forth. as and Jfor the purpose set forth.

2. The combination, With Athe trumpet, its D' W' HAYDEN supporting-lever, und the lever d, of the hin ged Witnesses stop y, provided with the auxiliary Weight g', JOSEPH A. MILLER7 the hinged link or connection j', the arm h, and JOSEPH A. MILLER, J r.
